Would factory resetting my laptop remove ProctorU software completely?

I'm doing an online course, and this shit seems incredibly invasive.

I plan to save my files, factory reset my laptop, do the online course, factory reset again, then put back the files I saved.

How much would factory resets actually remove this software?

I'm a tech noob, so yeah. Should I just switch to in-class learning (more commute)?
